Voxelay

Voxelay is a free multi fx and delay and echo and filter VST plugin developed by NOVUZEIT. Compatible OS(s): Windows.

Voxelay is a diverse effect plug-in designed explicitly to enhance vocals. Traditional chorus, delay, or reverb effects are possible with Voxelay, but more esoteric delay effects are a prime possibility – dub style echos, micro-burst comb-filtering, soprano choirs, and much more are easily obtained with Voxelay.

Voxelay consists of five independent delay layers which can be turned on and off individually. Each layer has the following self inclusive components:

Pitchshift with audio-buffer setting (plus LFO).

Vowel Filter for harmonic overtones.

Delay unit with timing-buffer offset.

Modulation with feedback setting.

Stereo Pan (plus LFO for Auto-Pan).

Stereo Width Offset.

Analog Filter with Cut-Off and Resonance controls.

Volume.

Wet/Dry mix.

Voxelay also has global volume and wet/dry settings, plus global clipping control, and a fully stereo global reverb.

VHL-3C

VHL-3C is a free equalizer VST, Audio Unit, AAX plugin developed by Black Rooster Audio. Compatible OS(s): Windows, macOS.

Built around a cascade of two constant-K filters the VHL-3C’s analog counterpart – a sought-after processor from the early 1950s – comprises an entirely passive design with very musical and interactive pass filters. Offering 3 simple and intuitive controls, the VHL-3C allows you to effectively remove rumble, hum or harsh frequencies from your signals. Set both filter knobs to their extreme positions and you’ll end up with a narrow telephone-line bandpass. “So what?”, you may wonder – Black Rooster Audio is giving away this goodie for free.

Features

Authentic Circuit Emulation

Our real time SPICE type component based circuit simulation approach allows to authentically capture the sound and feel of the analog counterpart in all nuances. Every crucial part of the passive filter network including filter stage interaction and the influence of different load resistances have been faithfully modeled.

SSE2 Optimized Code

DSP operations are pipelined using the SSE2 instruction set. This ensures highest possible performance operation despite very complex computations.

Auto-adjusted Oversampling For Maximum Audio Transparency

Aliasing artifacts are efficiently attenuated using a low latency linear phase Dolph-Chebyshev poly-phase design. The oversampling is auto-adjusted to your session’s sample rate to save valuable CPU power while offering the most transparent sound possible.

HighDPI / Retina Support

All our plug-Ins support high pixel density on Mac OS X and Windows to bring you the most enjoyable user experience on high DPI displays. Please refer to your manual to find whether your DAW is HighDPI capable if you’re working on Windows.

Triple EQ

Triple EQ is a free equalizer VST, VST3, Audio Unit, RTAS, AAX, DirectX plugin developed by Blue Cat Audio. Compatible OS(s): Windows 64b, macOS.

Blue Cat’s Triple EQ is an easy-to-use 3-band semi-parametric equalizer. It includes a low shelf filter, a high shelf filter and a boost/cut peak filter. Its wide range of gain (+/-40 dB per band) and bandwidth (.01 to 5 Octave) makes it very versatile. The three filters are linked together so that when you change the center frequency or the bandwidth, the three filter parameters are changed accordingly: you can change the entire equalizer characteristics with one single mouse click making any equalization task very easy and intuitive.

The graph shows the computed frequency response of the plug-in, so that you can exactly know how your signal is processed. This is not an approximated or “ideal” response curve based on the controls of the user interface, but the exact computed frequency response of the filter, which makes this plug-in a true WYSIWYG (What You See Is What You Get) equalizer.

Main Features:

WYSIWYG 3-band semi-parametric equalizer.

Filters designed after analog circuits.

+-40 dB range on each band.

Automatic gain compensation.

No latency.

Real time display of the frequency response.

Native DSP code for optimal performance.

Random preset generation: auto generate custom presets with one single click.

‘Smooth Update Mechanism’: real-time parameter modification with zipper-free parameter updates. Hear absolutely no ‘click’ when playing with parameters.

Full automation support (all parameters can be automated, with smooth and continuous update).

Any sample rate supported.

DirectX version: supports 32-bits floating point as well as 16 / 8 bits PCM audio streams.

Triple EQ supports “Blue Cat’s Skinning language”, allowing you to customize the plug-in to your own needs.

Toned

Toned is a free equalizer VST, VST3, Audio Unit, RTAS, AAX plugin developed by LVC-Audio. Compatible OS(s): Windows 64b, macOS.

Toned is a specialized tone shaping plugin with analog modeling. It is designed primarily for use in the mastering process or on two-track audio busses. Toned uses two distinct equalization processes: a three-band tone-shaping matrix, and a specially designed high pass (HP) filter.

The three-band tone-shaping matrix uses a crossover-style filter bank of first-order filters (-6dB per octave). This type of equalization produces very gentle and broad filtering, with minimal alteration of phase. Very wide boosts and cuts can be accomplished while still sounding natural. This style of equalization also mimics some of the interactions between frequency bands that are commonly found in passive analog EQs and analog tone controls. The tone-shaping matrix can be applied to stereo channels, or specifically to the mid or side channel. Additionally, Toned can be switched to use a two-band matrix.

The HP filter is specifically designed for accurately adjusting the low/sub bass energy. The filter has selectable Q and roll-off. The scale of the HP controls is specific to low bass, and ranges from 10 Hz to 50 Hz (with accuracy to 0.01 Hz). Just like the tone controls, the HP filter can be applied to the stereo channels, or specifically target the mid or side channel.

In addition to all of the tone and HP filter controls, Toned also includes an analog modeling engine to simulate the sound of hardware devices. The Toned analog sound consists of numerous parameters to simulate the unique frequency characteristics, saturation, self-noise, and other nuances of high-quality analog equipment. There is also a feedback control to simulate the effect of using negative feedback within an analog amplifier path.

Toned also includes many standard LVC-Audio features. This includes:

Delay and phase compensated mix control.

Adjustable input and output metering with peak and loudness meters.

Internal 64-bit precision with 2x fixed oversampling rate.

Knob controllers with fine- and superfine- control, and built-in A-B comparison.

System Requirements and Specifications:

Windows: VST, VST3, RTAS, and AAX plugin formats. Toned requires Windows XP SP 3 or newer with a processor that supports SSE2 (AMD or Intel processor from around 2004 or later). An iLok device is required to use the AAX format.

OS X: AU, VST, VST3, RTAS, and AAX plugin formats. Toned requires OS X 10.5 or later, and an Intel processor. An iLok device is required to use the AAX format.
